My First Pneumatic Gun Design

Unread postAuthor: Tyro » Sat Oct 07, 2006 11:59 pm

Here are some 3D pictures of what i wish to make, i'm sure you can tell what the parts are, some of the parts do not fit together like in my picture, but the design can still be seen.
It's going to be a fairly standard size rifle type gun.
And will not look entirly like the picture, i might upgrade the design.

You could have a stock on that cannon by adding an elbow to the back of the chamber and extending it to the hight of the cannon then you could either have that piece extenting downwards and having a 45* elbow with and endcap or have it going upwards and just put an end cap on it.

Then it will be easyer to fire :wink:

yeah, but my idea was to make my first one as cheap as i could, with the best performance i could get. i would prolly have to have a larger chamber for that, but that would cost me more in adaptors and larger Circum pipe. i might just put a strap on it! maybe make the barrel a bit shorter than in the picture, or extend the chamber a bit further towards the front.

Perspective view, i havn't added a blow gun in there because i'm still thinking of where to put it. And also thinking about what angle the valve should be at.

Side view of the gun, just so you can see the basic view.

if i wanted this rated for 200 PSI How much might it cost me, i'm think the PVC should fit into the Sprinkler valve, i'm not sure what size that is, but someone should know.

In canada this gun would be over $100. For the valve just get some threaded bushings that go to the size of the valve and use some close fitting nipples or if its the same size as PVC pipe just use some male adaptors. The threaded PVC bushings solvent weld to the pipe and on the other side have threaded hole to all different sizes.

The male Adaptor sounds the easiest. and, it wouldn't cost $100, it's not that big, the pipe would be no more then like 20 bux a meter, and i only need like 3 or a bit more, then i need some fittings, a blow gun and the valve.
